Embodiment 1

[0033] see figure 2 , figure 2 A schematic cross-sectional structure diagram of a first embodiment of a sound box assembly provided in an embodiment of the present invention, the sound box assembly includes: a sound box casing 1 , a speaker 2 and a passive radiator 3 .

[0034] Wherein, the sound box casing 1 includes an installation surface 11 on which the speaker 2 and the passive radiator 3 are disposed. The side opposite to the mounting surface 11 on the speaker shell 1 is the side where the speaker assembly emits sound to the outside.

[0035] The speaker assembly also includes a cantilever beam 6 and a support cover 34 connected to the passive radiator 3 , one end of the cantilever beam 6 is connected to the support cover 34 , and the other end of the cantilever beam 6 is connected to the speaker 2 . In this embodiment, the cantilever beam 6 is a steel sheet, which is used to transmit the vibration energy generated when the speaker 2 emits sound to the passive radiat...

Embodiment 2

[0050] see Figure 5 , Figure 5 The structure schematic diagram of the cantilever beam of the second embodiment of the sound box assembly provided by the embodiment of the present invention, the difference between the second embodiment and the first embodiment is that the cantilever beam 6 includes: steel sheet 61 and bonded to steel The rubber layer 62 on the sheet 61, one end of the steel sheet 61 is bonded to the loudspeaker 2, and the other end of the steel sheet 61 is bonded to the support cover 34. The rest of the structure of the sound box assembly is the same as that of the first embodiment, and will not be repeated here. repeat.

[0051] In this embodiment, the cantilever beam 6 is set as a structure in which a steel sheet 61 is pasted with a rubber layer 62. Due to its rigidity, the steel sheet 61 can quickly transmit the vibration energy generated by the speaker 2 to the passive radiator 3, while the rubber layer 62 is a viscoelastic material, which can quickly c...

Embodiment 3

[0054] see Figure 6 and Figure 7 , Figure 6 and Figure 7 The schematic diagram of the external structure and the schematic diagram of the internal structure of the third embodiment of the speaker assembly provided by the embodiment of the present invention. The difference between the third embodiment and the first embodiment is that the side of the speaker housing 1 is provided with mounting ears. 4. A slot 41 is provided on the end face of the mounting ear 4, and a vibration isolation washer 5 is provided in the slot 41. The rest of the structure of the speaker assembly is the same as that of the first embodiment, and will not be repeated here.

[0055] In this embodiment, the sound box housing 1 can be assembled with the rest of the sound box assembly through the mounting ear 4, and the material of the vibration isolation gasket 5 can be rubber. By setting the vibration isolation gasket 5 in the installation ear 4 of the sound box housing 1 In the vibration energy gen...

Abstract

The embodiment of the invention discloses a sound box component, a sound box and display equipment. The sound box component comprises a sound box shell, a loudspeaker, a passive radiator, a cantilever beam and a support cover, wherein the sound box shell comprises a mounting surface; the loudspeaker and the passive radiator are arranged on the mounting surface; the support cover is connected with the passive radiator; and one end of the cantilever beam is connected with the support cover, and the other end of the cantilever beam is connected with the loudspeaker. The cantilever beam, the passive radiator and the support cover construct one dynamic vibration absorber, so that vibration energy generated by sounding of the loudspeaker is transmitted to the passive radiator through the cantilever beam; most vibration energy transmitted to the sound box shell by the loudspeaker is consumed by the vibration of the passive radiator; the vibration energy transmitted to the sound box shell by the loudspeaker is lowered; vibration of the sound box shell is lowered; noise caused by vibration of the sound box shell is reduced; the machine vibration phenomenon caused by vibration energy transmitted to an overall structure by the sound box shell is avoided; and the sound experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a sound box assembly, a sound box and a display device. Background technique [0002] Speaker components are an important part of electronic products such as televisions, and are usually used to convert electrical signals into acoustic signals and send the acoustic signals to the outside of electronic products. The sound quality of speaker components directly affects the user experience of the sound quality of electronic products such as TVs. [0003] see figure 1 , the existing speaker assembly generally includes a speaker case 1 , a speaker 2 and a passive radiator 3 disposed inside the speaker case 1 . Wherein, the speaker 2 generally includes a speaker fixed side, a speaker suspension side, a speaker diaphragm, a voice coil, a speaker bracket and a driving magnet. The structure of the passive radiator 3 is similar to that of the loudspeaker 2. Compared with the lou...
